Abstract

The invention relates to a propulsion device (2) for a vehicle, which device (2) comprises an output shaft (14) of a combustion engine (4), an input shaft (27) of a gearbox (8), an electrical machine (6) which comprises a stator (24) and a rotor (26), and a planetary gear (10) which comprises movable components (18, 20, 22). A locking sleeve (38) is movable between first and second positions, in which first position the engine output shaft (14) and the gearbox input shaft (27) are allowed to rotate at different speeds via the planetary gear (10), and in which second position the locking sleeve (38) firmly connects the engine output shaft (14) to the gearbox input shaft (27) via the planetary gear (10). The invention relates also to a method for controlling such a propulsion device (2).

Description

ment. För det fall den elektriska maskinens högsta moment är lägre än forbrännings- motoms högsta moment kommer den elektriska maskinen inte förrnå att alstra ett till- räckligt stort reaktionsmoment till planetväxeln, vilket medför att förbränningsmotom inte kan överföra sitt högsta vridmoment till växellådan och vidare till fordonets driv- hjul. Därmed är det högsta överförbara momentet till växellådan begränsat av den elektriska maskinens styrka. Speciellt, då kraftig acceleration av fordonet önskas och den elektriska maskinen inte förmår att alstra tillräckligt stort reaktionsmoment kom- mer värme att alstras i den elektriska maskinen på ett oönskat sätt. ment. In the event that the maximum torque of the electric machine is lower than the maximum torque of the internal combustion engine, the electric machine will not be able to generate a sufficiently large reaction torque to the planetary gear, which means that the internal combustion engine can not transmit its maximum torque to the gearbox - wheels. Thus, the highest transferable torque to the gearbox is limited by the strength of the electric machine. Especially, when strong acceleration of the vehicle is desired and the electric machine is not able to generate a sufficiently large reaction moment, heat will be generated in the electric machine in an undesired manner.

Dokumentet US-Al- 2003/0078127 visar ett drivsystem for ett fordon med en förbrän- ningsmotor och en elektrisk motor, vilka är sammankopplade med en planetväxel. Pla- netväxelns planethjulshållare är ansluten till en ingående axel i en växellåda. Planet- hjulshållaren och planetväxelns solhjul kan fast förbindas med en hylsa, så att den elektriska motorn och växellådans ingående axel kan rotera som en fast roterande en- het.The document US-Al-2003/0078127 shows a drive system for a vehicle with an internal combustion engine and an electric motor, which are connected to a planetary gear. The planetary gear holder of the planetary gear unit is connected to an input shaft in a gearbox. The planetary gear holder and the planetary gear's sun gear can be fixedly connected to a sleeve, so that the electric motor and the input shaft of the gearbox can rotate as a fixed rotating unit.

I ett fordon är det tillgängliga utrymmet för drivanordningen ofta begränsat. Om driv- anordningen innefattar ett flertal komponenter, såsom en forbränningsmotor, en elekt- risk maskin, en växellåda och en planetväxel måste konstruktionen vara kompakt. Av den anledningen är det ett önskemål att den elektriska maskinens dimensioner är små, vilket medför att den elektriska maskinens effekt och högsta möjliga alstrade moment begränsas.In a vehicle, the available space for the drive device is often limited. If the drive device comprises a number of components, such as an internal combustion engine, an electric machine, a gearbox and a planetary gear, the construction must be compact. For this reason, it is desirable that the dimensions of the electric machine be small, which means that the power of the electric machine and the highest possible generated torque are limited.

Det ställs också krav på hög tillförlitlighet och hög driftsäkerhet hos de komponenter som igår i drivanordningen samt att de i drivanordningen ingående komponentema kan överföra ett stort vridmoment samtidigt som de uppvisar små dimensioner och låg vikt.There are also requirements for high reliability and high reliability of the components that were in the drive device yesterday and that the components included in the drive device can transmit a large torque at the same time as they have small dimensions and low weight.

SAMMANFATTNING AV UPPFINNINGEN Syftet med föreliggande uppfinning är att tillhandahålla drivanordning för ett fordon, vilken drivanordning har en kompakt konstruktion.SUMMARY OF THE INVENTION The object of the present invention is to provide a drive device for a vehicle, which drive device has a compact construction.

Ett ytterligare syfte med uppfinningen är att tillhandahålla en drivanordning för ett fordon, vilken drivanordning har hög tillförlitlighet och hög driftsäkerhet. Ännu ett syfte med uppfinningen är att tillhandahålla en drivanordning för ett fordon med momentöverförande komponenter, som uppvisar små dimensioner och låg vikt.A further object of the invention is to provide a drive device for a vehicle, which drive device has high reliability and high operational reliability. Yet another object of the invention is to provide a drive device for a vehicle with torque transmitting components which have small dimensions and low weight.

Dessa syften uppnås med drivanordningen av det inledningsvis nämnda slaget, vilken kännetecknas av de särdrag som anges i patentkravets 1 kännetecknande del.These objects are achieved with the drive device of the kind mentioned in the introduction, which is characterized by the features stated in the characterizing part of claim 1.

Dessa syften uppnås även med ett förfarande för att styra drivanordningen av det in- ledningsvis nämnda slaget, vilket kännetecknas av de särdrag som anges i patentkra- vets 13 kännetecknande del.These objects are also achieved with a method for controlling the drive device of the type mentioned in the introduction, which is characterized by the features stated in the characterizing part of claim 13.

Genom att med låshylsan fast förbinda förbränningsmotorns utgående axel med växel- lådans ingående axel via planetväxeln kan en önskad acceleration av fordonet erhållas samtidigt som den elektriska maskinens dimensioner och effekt kan begränsas, vilket medför en kompakt drivanordning med begränsade dimensioner. Därmed kan också det högsta vridmoment som den elektriska maskinen kan alstra vara lägre än det högsta vridmoment som förbränningsmotorn kan alstra. Genom att med låshylsan fast förbin- da förbränningsmotoms utgående axel med växellådans ingående axel via planetväxeln kan en stor momentarrn erhållas, vilket medför att låshylsan och även komponenter hos planetväxeln kan utformas med små dimensioner och låg vikt.By firmly connecting the output shaft of the internal combustion engine to the input shaft of the gearbox via the planetary gear with the locking sleeve, a desired acceleration of the vehicle can be obtained while the dimensions and power of the electric machine can be limited, resulting in a compact drive with limited dimensions. Thus, the highest torque that the electric machine can generate can also be lower than the highest torque that the internal combustion engine can generate. By permanently connecting the output shaft of the internal combustion engine to the input shaft of the gearbox via the planetary gear with the locking sleeve, a large torque can be obtained, which means that the locking sleeve and also components of the planetary gear can be designed with small dimensions and low weight.

Enligt en utföringsforrn av uppfinningen innefattar låshylsan splines, som i det första läget ingriper med splines hos en första rörlig komponent hos planetväxeln och i det andra läget även ingriper med splines anordnade på en hos planetväxeln andra rörlig komponent. Därmed kan låshylsan och planethållaren utformas med små dimensioner ”IO och låg vikt. Ett splinesförband medför också att en kompakt konstruktion, som också har en hög tillförlitlighet och en hög driftsäkerhet kan erhållas.According to an embodiment of the invention, the locking sleeve comprises splines which in the first position engage with splines of a first movable component of the planetary gear and in the second position also engage with splines arranged on a second moving component of the planetary gear. Thus, the locking sleeve and the planet holder can be designed with small dimensions “IO and low weight. A spline joint also means that a compact design, which also has a high reliability and a high operational reliability can be obtained.

Enligt en ytterligare utföringsform innefattar låshylsan minst ett urtag i vilket minst en tapp på den första rörliga komponenten är utformad att ingripa. Med urtaget och tap- pen erhålls en tillförlitlig förflyttning av låshylsan mellan de första och andra lägena.According to a further embodiment, the locking sleeve comprises at least one recess in which at least one pin on the first movable component is designed to engage. With the recess and the pin, a reliable one is obtained for fl moving the locking sleeve between the first and second positions.

Enligt en ytterligare utföringsforrn är det minst ena urtaget i låshylsan så utformat att låshylsan kvarhålls i det andra läget när den minst ena tappen är införd i ett i urtaget utformat låsparti och när låshylsan och den andra rörliga komponenten roterar kring en gemensam rotationsaxel. Därmed behövs inga ytterligare medel för att kvarhålla lås- hylsan i det andra läget, vilket medför en kompakt konstruktion samt en hög tillförlit- lighet och en hög driftsäkerhet.According to a further embodiment, the at least one recess in the locking sleeve is designed such that the locking sleeve is retained in the second position when the at least one pin is inserted in a locking portion formed in the recess and when the locking sleeve and the other movable component rotate about a common axis of rotation. Thus, no additional means are needed to retain the locking sleeve in the second position, which results in a compact design as well as a high reliability and a high operational reliability.

En planetväxel innefattar vanligtvis tre komponenter som är roterbart anordnade i för- hållande till varandra nämligen ett solhjul, en planethjulhållare och ett ringhjul. Med kännedom om antal kuggar hos solhjulet och ringhjulet kan de inbördes varvtalen hos de tre komponentema bestämmas under drift. Enligt föreliggande uppfinning är en av planetväxelns komponenter förbunden med en utgående axel hos förbränningsmotom.A planetary gear usually comprises three components which are rotatably arranged in relation to each other, namely a sun gear, a planet gear holder and a ring gear. With knowledge of the number of teeth of the sun gear and the ring gear, the mutual speeds of the three components can be determined during operation. According to the present invention, one of the components of the planetary gear is connected to an output shaft of the internal combustion engine.

Denna komponent hos planetväxeln roterar således med ett varvtal som motsvarar varvtalet hos den utgående axeln hos förbränningsmotom. En andra komponent hos planetväxeln är förbunden med en ingående axel till växellådan. Denna komponent hos planetväxeln roterar således med samma varvtal som den ingående axeln till växellå- dan. En tredje komponent hos planetväxeln är förbunden med en rotor hos en elektrisk maskin. Denna komponent hos planetväxeln roterar således med samma varvtal som rotom hos den elektriska maskinen om de är direkt förbundna med varandra. Altema- tivt kan den elektriska maskinen vara förbunden med den tredje komponenten hos pla- netväxeln via en transmission som har en utväxling. I detta fall kan den elektriska ma- skinen och den tredje komponenten hos planetväxeln rotera med olika varvtal. Varvta- let hos elektriska maskiner kan regleras steglöst. Under driftstillfällen då den ingående axeln till växellådan ska ges ett önskat varvtal beräknar en styrenhet, med kännedom om förbränningsmotoms varvtal, det varvtal som den tredje komponenten måste drivas med för att den ingående axeln till växellådan ska erhålla det önskade varvtalet. En styrenhet aktiverar den elektriska maskinen så att den ger den tredje komponenten det beräknade varvtalet och därmed den ingående axeln till växellådan det önskade varvta- let.This component of the planetary gear thus rotates at a speed corresponding to the speed of the output shaft of the internal combustion engine. A second component of the planetary gearbox is connected to an input shaft of the gearbox. This component of the planetary gearbox thus rotates at the same speed as the input shaft of the gearbox. A third component of the planetary gear is connected to a rotor of an electric machine. This component of the planetary gear thus rotates at the same speed as the rotor of the electric machine if they are directly connected to each other. Alternatively, the electrical machine may be connected to the third component of the planetary gear via a transmission having a gear ratio. In this case, the electric machine and the third component of the planetary gear can rotate at different speeds. The speed of electrical machines can be regulated steplessly. During operating times when the input shaft to the gearbox is to be given a desired speed, a control unit calculates, with knowledge of the combustion engine speed, the speed at which the third component must be driven in order for the input shaft of the gearbox to obtain the desired speed. A control unit activates the electric machine so that it gives the third component the calculated speed and thus the input shaft to the gearbox the desired speed.

DETALJERAD BESKRIVNING AV EN FÖREDRAGEN UTFÖRINGSFORM AV UPPFINNINGEN Fig. 1 visar en sidovy av ett fordon l, som innefattar en drivanordning 2 enligt förelig- gande uppfmning. En förbränningsmotor 4 är kopplad till en elektrisk maskin 6 och en växellåda 8 via en planetväxel 10. Växellådan 8 är vidare kopplad till fordonets 1 driv- hjul 12.DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION Fig. 1 shows a side view of a vehicle 1, which comprises a drive device 2 according to the present invention. An internal combustion engine 4 is connected to an electric machine 6 and a gearbox 8 via a planetary gear 10. The gearbox 8 is further connected to the drive wheel 12 of the vehicle 1.

Fig. 2 visar en tvärsnittsvy av drivanordningen 2 enligt föreliggande uppfinning. Pla- netväxeln 10 innefattar rörliga komponenter i forrn av ett solhjul 18, ett ringhjul 20 och en planethjulhållare 22. Solhjulet 18 är enligt den visade utföringsformen samman- kopplat med förbränningsmotorns 4 utgående axel 14 och utgör en sammanhängande enhet. Det är också möjligt att sammankoppla förbränningsmotoms 4 utgående axel 14 med ringhjulet 20 eller planethjulhållaren 22. Solhjulet 18 sammankopplas då med den elektriska maskinen 6 eller växellådan 8. Olika utväxlingsförhållanden erhålles bero- ende på vilka komponenter hos planetväxeln 10, som sammankopplas med förbrän- ningsmotom 4, den elektriska maskinen 6 eller växellådan 8.Fig. 2 shows a cross-sectional view of the drive device 2 according to the present invention. The planetary gear 10 comprises movable components in the form of a sun gear 18, a ring gear 20 and a planet gear holder 22. According to the embodiment shown, the sun gear 18 is coupled to the output shaft 14 of the internal combustion engine 4 and forms a continuous unit. It is also possible to connect the output shaft 14 of the internal combustion engine 4 to the ring gear 20 or the planet gear holder 22. The sun gear 18 is then connected to the electric machine 6 or the gearbox 8. Different gear ratios are obtained depending on which components of the planetary gear 10 are connected to the internal combustion engine. 4, the electric machine 6 or the gearbox 8.

Den elektriska maskinen 6 innefattar en stator 24 och en rotor 26. Statorn 24 är fast förbunden med fordonet l och roterar därför inte. Rotorn 26 är kopplad till planetväx- elns 10 ringhjul 20 och kan således rotera i förhållande till statom 24. Enligt det visade utföringsexemplet utgör ringhjulet 20 och den elektriska maskinens 6 rotor 26 en sammanhängande enhet. Det är också möjligt att utföra ringhjulet 20 och rotom 26 som separata enheter, vilka är förbundna med varandra.The electric machine 6 comprises a stator 24 and a rotor 26. The stator 24 is fixedly connected to the vehicle 1 and therefore does not rotate. The rotor 26 is coupled to the ring gear 20 of the planetary gear 10 and can thus rotate relative to the stator 24. According to the embodiment shown, the ring wheel 20 and the rotor 26 of the electric machine 6 form a continuous unit. It is also possible to design the ring gear 20 and the rotor 26 as separate units, which are connected to each other.

En ingående axel 27 hos växellådan 8 är kopplad till planethjulshållaren 22, som inne- fattar ett antal kugghjul, som benämns planethjul 28. Dessa är lagrade på planethjuls- hållaren 22 med exempelvis rullningslager 36. I den visade utforingsformen är även solhjulet 18 lagrat på planethjulshållaren 22 med rullningslager 37. Planethjulens 28 kuggar 30 ingriper med kuggar 32, 34, som är utformade på solhjulet 18 resp. ringhju- let 20.An input shaft 27 of the gearbox 8 is coupled to the planet gear holder 22, which comprises a number of gears, called planet gears 28. These are mounted on the planet gear holder 22 with, for example, roller bearings 36. In the embodiment shown, the sun gear 18 is also mounted on the planet gear holder. 22 with roller bearings 37. The teeth 30 of the planet gears 28 engage with teeth 32, 34, which are formed on the sun gear 18 resp. ring gear 20.

Vid motorbromsning släpper föraren fordonets 1 gaspedal (inte visad). Växellådans 8 ingående axel 27 driver då den elektriska maskinen 6 samtidigt som förbränningsmo- tom 4 och den elektriska maskinen 6 motorbromsar. Den elektriska maskinen 6 gene- rerar här elektrisk energi som lagras i ett batteri 50 i fordonet. Detta drifttillstånd be- nämns regenerativ brornsning. Den elektriska maskinen 6 som fungerar därmed som en generator. När den elektriska maskinen 6 fiangerar som en generator utövar den elekt- riska maskinen 6 ett motverkande vridmoment på vridmomentet från växellådan 8, vilket resulterar i att fordonet 1 bromsas, eftersom växellådan 8 är kopplad till fordo- nets 1 drivhjul 12.During engine braking, the driver releases the vehicle's accelerator pedal (not shown). The input shaft 27 of the gearbox 8 then drives the electric machine 6 at the same time as the internal combustion engine 4 and the electric machine 6 engine brakes. The electrical machine 6 here generates electrical energy which is stored in a battery 50 in the vehicle. This operating condition is called regenerative burning. The electric machine 6 which thus functions as a generator. When the electric machine 6 fi indicates as a generator, the electric machine 6 exerts a counteracting torque on the torque from the gearbox 8, which results in the vehicle 1 being braked, since the gearbox 8 is coupled to the drive wheel 12 of the vehicle 1.

Vid acceleration av fordonet 1 skall ett ökat vridmoment levereras från förbrännings- motorn 4 och den elektriska maskinen 6 till växellådan 8 och vidare till fordonets 1 drivhjul 12. Eftersom både förbränningsmotom 4 och den elektriska maskinen 6 är sammankopplade med planetväxeln 10 kommer det största möjliga momentet som levereras av förbränningsmotom 4 och den elektriska maskinen 6 att begränsas av nå- gon av dessa drivenheter 4, 6 vars högsta moment är lägre än den andra drivenhetens 4, 6 högsta moment. För det fall den elektriska maskinens 6 högsta moment är lägre än förbränningsmotoms 4 högsta moment kommer den elektriska maskinen 6 inte förmå att alstra ett tillräckligt stort reaktionsmoment till planetväxeln 10, vilket medför att förbränningsmotom 4 inte kan överföra sitt högsta vridmoment till växellådan 8 och vidare till fordonets 1 drivhjul 12. Därmed är det högsta överförbara momentet till växellådan 8 begränsat av den elektriska maskinens 6 styrka. Speciellt, då kraftig acce- leration av fordonet 1 önskas och den elektriska maskinen 6 inte förmår att alstra till- räckligt stort reaktionsmoment kommer värme att alstras i den elektriska maskinen 6 på ett oönskat sätt.When accelerating the vehicle 1, an increased torque shall be delivered from the internal combustion engine 4 and the electric machine 6 to the gearbox 8 and further to the drive wheels 12 of the vehicle 1. Since both the internal combustion engine 4 and the electric machine 6 are connected to the planetary gear 10, the greatest possible torque supplied by the internal combustion engine 4 and the electric machine 6 to be limited by any of these drive units 4, 6 whose maximum torque is lower than the highest torque of the other drive unit 4, 6. If the maximum torque of the electric machine 6 is lower than the highest torque of the internal combustion engine 4, the electric machine 6 will not be able to generate a sufficiently large reaction torque to the planetary gear 10, which means that the internal combustion engine 4 can not transmit its maximum torque to the gearbox 8 and on to the drive wheel 12 of the vehicle 1. Thus, the highest transferable torque to the gearbox 8 is limited by the strength of the electric machine 6. In particular, when strong acceleration of the vehicle 1 is desired and the electric machine 6 is not able to generate a sufficiently large reaction moment, heat will be generated in the electric machine 6 in an undesired manner.

Genom att fast förbinda förbränningsmotoms 4 utgående axel 14 med växellådans 8 ingående axel 27 med en låshylsa 38 via planetväxeln 10 kan en önskad acceleration av fordonet 1 erhållas samtidigt som den elektriska maskinens 6 dimensioner och ef- fekt kan begränsas, vilket medför en kompakt drivanordning 2 med begränsade dimen- sioner. Därmed kan också det högsta vridmoment som den elektriska maskinen 6 kan alstra vara lägre än det högsta vridmoment som förbränningsmotom 4 kan alstra.By firmly connecting the output shaft 14 of the internal combustion engine 4 to the input shaft 27 of the gearbox 8 to a locking sleeve 38 via the planetary gear 10, a desired acceleration of the vehicle 1 can be obtained while the dimensions and power of the electric machine 6 can be limited, resulting in a compact drive 2 with limited dimensions. Thus, the highest torque that the electric machine 6 can generate can also be lower than the highest torque that the internal combustion engine 4 can generate.

Låshylsan 38 är flyttbar mellan ett första och andra läge. I det första läget medges för- bränningsmotoms 4 utgående axel 14 och växellådans 8 ingående axel 27 att rotera med olika varvtal via planetväxeln 10. I ett andra läge förbinder låshylsan 38 förbrän- ningsmotoms 4 utgående axel 14 fast med växellådans 8 ingående axel 27 via planet- växeln l0.The locking sleeve 38 is fl surface between a first and a second position. In the first position the output shaft 14 of the internal combustion engine 4 and the input shaft 27 of the gearbox 8 are allowed to rotate at different speeds via the planetary gear 10. In a second position the locking sleeve 38 connects the output shaft 14 of the internal combustion engine 4 to the input shaft 27 of the gearbox 8 via the plane - gear l0.

Låshylsan 38 innefattar splines 64, som i det första läget ingriper med splines 66, som är utformade på ringhjulet 20. I ett andra läge kan låshylsans 38 splines 66 även ingri- pa med splines 68, som är utformade på planethjulshållaren 22. Låshylsan 38 är utfor- mad som en ringforrnad hylsa, som kan väsentligen koncentriskt omsluta ett parti 47 av ringhjulets 20 periferi och ett parti 49 av planethjulshållarens 22 periferi. Låshyl- sans 38 splines 64 är utformade på en inre omkrets av låshylsan 38 och har en axiell utbredning som medför att låshylsans 38 splines 64 samtidigt kan ingripa med ringhju- lets 20 och planethjulshållarens 22 splines. De splines 66 som är utformade i ringhjulet är företrädesvis utformade i en yttre periferi av ringhjulet 20. De splines 68 som är utformade i planethjulshållaren 22 är företrädesvis utformade i en yttre periferi av pla- nethjulshållaren 22. Därmed erhålles en stor momentarm för överförande av vridmo- ment av låshylsan 38.The locking sleeve 38 comprises splines 64, which in the first position engage with splines 66, which are formed on the ring wheel 20. In a second position, the splines 66 of the locking sleeve 38 can also engage with splines 68, which are formed on the planetary gear holder 22. The locking sleeve 38 is formed as an annular sleeve which can substantially concentrically enclose a portion 47 of the periphery of the ring gear 20 and a portion 49 of the periphery of the planet gear holder 22. The splines 64 of the locking sleeve 38 are formed on an inner circumference of the locking sleeve 38 and have an axial extension which means that the splines 64 of the locking sleeve 38 can simultaneously engage with the splines of the ring gear 20 and the planetary gear holder 22. The splines 66 formed in the ring gear are preferably formed in an outer periphery of the ring gear 20. The splines 68 formed in the planet gear holder 22 are preferably formed in an outer periphery of the planet wheel holder 22. Thereby a large torque arm for transmitting rotary gear is obtained. meant by the locking sleeve 38.

Förbränningsmotoms 4 utgående axel 14, rotom 26 hos den elektriska maskinen 6, växellådans 8 ingående axel 27 och låshylsan 28 är roterbart anordnade kring en gemensam rotationsaxel 48.The output shaft 14 of the internal combustion engine 4, the rotor 26 of the electric machine 6, the input shaft 27 of the gearbox 8 and the locking sleeve 28 are rotatably arranged about a common axis of rotation 48.

Låshylsan 38 är axiellt förskjutbar utmed ringhjulets 20 periferi och planethjulshålla- rens 22 periferi vid förflyttningen mellan det första och andra läget. En manövergaffel 53 är anordnad att flytta låshylsan 38 mellan det första och andra läget. Manövergaf- feln 53 löper i ett i låshylsans 38 yttre periferi utformat spår 62. Företrädesvis styrs manövergaffeln 53 av en pneumatisk cylinder 54, som är kopplad till en tryckluftskälla 56. Den pneumatiska cylindern 54 innefattar en kolvstång 57 på vilken manövergaffeln 53 är anordnad.The locking sleeve 38 is axially displaceable along the periphery of the ring gear 20 and the periphery of the planet gear holder 22 at the displacement between the first and second position. An operating fork 53 is arranged to move the locking sleeve 38 between the first and second positions. The operating fork 53 runs in a groove 62 formed in the outer periphery of the locking sleeve 38. Preferably, the operating fork 53 is guided by a pneumatic cylinder 54, which is connected to a source of compressed air 56. The pneumatic cylinder 54 comprises a piston rod 57 on which the operating fork 53 is arranged.

För att förskjuta och förflytta låshylsan 38 från det första till det andra läget styrs för- bränningsmotom 4 och den elektriska maskinen 6 så att ett momentlöst tillstånd bildas mellan förbränningsmotoms 4 utgående axel 14 och planetväxeln 10. Till detta an- vänds en styrenhet 55 som också är anpassad att styra den elektriska maskinen 6 så att den under vissa tillämpliga driftstillfällen utnyttjar lagrad elektrisk energi för att tillfö- ra drivkraft till växellådans 8 ingående axel 27 och under andra driftstillfällen utnyttjar växellådans 8 ingående axels 27 rörelseenergi för att utvinna och lagra elektrisk energi.To displace and move the locking sleeve 38 from the first to the second position, the internal combustion engine 4 and the electric machine 6 are controlled so that a torque-free state is formed between the output shaft 14 of the internal combustion engine 4 and the planetary gear 10. A control unit 55 is also used for this. is adapted to control the electric machine 6 so that during certain applicable operating times it uses stored electrical energy to supply driving force to the input shaft 27 of the gearbox 8 and during other operating uses the input shaft 27 of the input shaft 27 of the gearbox 8 to extract and store electrical energy.

Styrenheten 55 avkänner således varvtal och/eller vridmoment hos förbränningsmo- torns 4 utgående axel 14, växellådans 8 ingående axel 27 och den elektriska maskinens 6 rotor 26, för att därmed styra förbränningsmotom 4 och den elektriska maskinen 6 så att ett momentlöst tillstånd bildas mellan förbränningsmotoms 4 utgående axel 14 och växellådans ingående axel 27. När det momentlösa tillståndet uppnåtts förskjuts och förflyttas låshylsan 38 till det andra läget genom att styrenheten aktiverar tryckluftskäl- lan 56, som via en ledning 58 tillför trycklufien till den pneumatiska cylindern 54, så att cylindem 54 skjuter låshylsan 38 med hjälp av gaffeln 53. Styrenheten 55 är kopp- lad till förbränningsmotom 4, växellådan 8, den elektriska maskinen 6 och tryckluft- källan 56 via elektriska ledare 60. Styrenheten 55 styr därmed förflyttningen av låshyl- san 38. Det är också möjligt att anordna en separat styrenhet för tryckluftkällan 56.The control unit 55 thus senses speed and / or torque of the output shaft 14 of the internal combustion engine 4, the input shaft 27 of the gearbox 8 and the rotor 26 of the electric machine 6, so as to control the internal combustion engine 4 and the electric machine 6 so that a torqueless state is formed between the internal combustion engine. 4 output shaft 14 and gearbox input shaft 27. When the torqueless state is reached, the locking sleeve 38 is displaced and moved to the second position by the control unit activating the compressed air source 56, which supplies the compressed cap to the pneumatic cylinder 54 via a line 58, so that the cylinder 54 pushes the locking sleeve 38 by means of the fork 53. The control unit 55 is connected to the internal combustion engine 4, the gearbox 8, the electric machine 6 and the compressed air source 56 via electrical conductors 60. The control unit 55 thus controls the movement of the locking sleeve 38. It is also it is possible to arrange a separate control unit for the compressed air source 56.

Styrenheten 55 är således anpassad att styra låshylsan 38 och även anpassad att avgöra vid vilka tillfällen som den elektriska maskinen 6 ska arbeta som motor och vid vilka tillfällen som den ska arbeta som generator. För att avgöra detta kan styrenheten 55 mottaga aktuell information från ovan angivna lämpliga driftsparametrar. Styrenheten 55 kan vara en dator med lämplig programvara för detta ändamål. Styrenheten 55 styr även flödet av elektrisk energi mellan ett batteri 50 och den elektriska maskinens 6 stator 24. Vid tillfällen som den elektriska maskinen 6 arbetar som motor tillförs lagrad elektrisk energi från batteriet 50 till statom 24. Vid tillfällen som den elektriska maski- nen 6 arbetar som generator tillförs elektrisk energi från statom 24 till batteriet 50.The control unit 55 is thus adapted to control the locking sleeve 38 and also adapted to determine at which times the electric machine 6 should operate as a motor and at which occasions it should operate as a generator. To determine this, the control unit 55 can receive current information from the above-mentioned suitable operating parameters. The control unit 55 may be a computer with suitable software for this purpose. The control unit 55 also controls the flow of electrical energy between a battery 50 and the stator 24 of the electric machine 6. At times when the electric machine 6 operates as a motor, stored electrical energy is supplied from the battery 50 to the stator 24. At times when the electric machine 6 acting as a generator, electrical energy is supplied from the stator 24 to the battery 50.

Fig. 3 visar en tvärsnittsvy av drivanordningen 2 enligt föreliggande uppfinning med låshylsan i det andra läget. I det andra läget är förbränningsmotoms 4 utgående axel 14 och växellådans 8 ingående axel 27 fast förbundna med varandra med låshylsan 38 via ”IO planetväxeln 10. För att möjliggöra denna förflyttning av låshylsan 38 har styrenheten 55 först styrt förbränningsmotorn 4 och den elektriska maskinen 6 så att ett moment- löst tillstånd bildats mellan förbränningsmotoms 4 utgående axel 14 och växellådans ingående axel 27, vilket förklarats ovan i samband med fig. 2.Fig. 3 shows a cross-sectional view of the drive device 2 according to the present invention with the locking sleeve in the second position. In the second position, the output shaft 14 of the internal combustion engine 4 and the input shaft 27 of the gearbox 8 are fixedly connected to each other with the locking sleeve 38 via the planetary gear 10. To enable this movement of the locking sleeve 38, the control unit 55 first controls the internal combustion engine 4 and the electric machine 6. that a torque-free state is formed between the output shaft 14 of the internal combustion engine 4 and the input shaft 27 of the gearbox, which is explained above in connection with Fig. 2.

När fordonet l accelererats till önskad hastighet styrs manövergaffeln 53 så att låshyl- san 38 återförs till det första läget. Samtidigt styrs förbränningsmotom 4 och den elekt- riska maskinen 6 av styrenheten 55 så att ett momentlöst tillstånd bildas mellan för- bränningsmotorns 4 utgående axel 14 och växellådans 8 ingående axel 27. När det momentlösa tillståndet uppnåtts förskjuts och förflyttas låshylsan 38 till det första lä- get. När låshylsan 38 har återförts till det första läget kan fordonet 1 drivas av både förbränningsmotorn 4 och den elektriska maskinen 6.When the vehicle 1 has been accelerated to the desired speed, the control fork 53 is controlled so that the locking sleeve 38 is returned to the first position. At the same time, the internal combustion engine 4 and the electric machine 6 are controlled by the control unit 55 so that a torque-free state is formed between the output shaft 14 of the internal combustion engine 4 and the input shaft 27 of the gearbox 8. When the torque-free state is reached, the locking sleeve 38 is moved to the first load. get. When the locking sleeve 38 has been returned to the first position, the vehicle 1 can be driven by both the internal combustion engine 4 and the electric machine 6.

Fig. 4 visar en vy i perspektiv av låshylsan 38 enligt föreliggande uppfinning. Låshyl- san 38 är utformad som en ringforrnad hylsa med splines 64, som är utformade på en inre omkrets av låshylsan 38. Det framgår även hur spåret 62 för manövergaffeln är utformat i låshylsans 38 yttre periferi. I den inre omkretsytan är låshylsan 38 försedd med minst ett urtag 42 i vilket minst en tapp 40 på ringhjulets yttre periferi är utformad att ingripa, vilket framgår av figurerna 2 och 3. I fig. 4 är tre urtag 42 anordnade och jämnt fördelade i låshylsan 38. Tappama 40 skall anordnas med motsvarande antal och fördelning på ringhjulets 20 periferi. Urtagen 42 har en axiell utbredning och är så ut- formade att låshylsan 38 kvarhålls i det andra läget när tappama 40 är införda i ett i urtagen 42 utformat låsparti 70.Fig. 4 shows a perspective view of the locking sleeve 38 according to the present invention. The locking sleeve 38 is designed as an annular sleeve with splines 64, which are formed on an inner circumference of the locking sleeve 38. It can also be seen how the groove 62 for the operating fork is formed in the outer periphery of the locking sleeve 38. In the inner circumferential surface the locking sleeve 38 is provided with at least one recess 42 in which at least one pin 40 on the outer periphery of the ring wheel is designed to engage, as shown in Figures 2 and 3. In Fig. 4 three recesses 42 are arranged and evenly distributed in the locking sleeve. 38. The pins 40 shall be arranged with the corresponding number and distribution on the periphery of the ring wheel 20. The recesses 42 have an axial extension and are designed such that the locking sleeve 38 is retained in the second position when the pins 40 are inserted into a locking portion 70 formed in the recesses 42.

Fig. 5 visar en detaljvy av ett urtag 42 i låshylsan 38 enligt föreliggande uppfinning.Fig. 5 shows a detail view of a recess 42 in the locking sleeve 38 according to the present invention.

Urtaget 42 utbreder sig i låshylsans 38 axiella utsträckning. Urtaget 42 är försett med ett långsträckt parti 72 med väsentligen parallella motstående första väggytor 74, vilka är belägna på ett avstånd som är större än både tappens 40 diameter och spelet i spli- nesförbandet 64, 66, 68. På så sätt undviks att tappen 40 i det första läget ligger och skaver mot de första väggytoma 74 i urtaget 42. Det långsträckta partiet 72 övergår i ett låsparti 70, som uppvisar på avstånd från varandra belägna motstående andra vägg- ytor 76, som har en radie, som väsentligen motsvarar tappens 40 radie. Låspartiets 70 11 andra väggytor 76 är belägna på ett avstånd från varandra som överstiger tappens 40 diameter. Låsparitet 70 placeras så i för hållande till låshylsans 38 splines 64 att då tappen 40 är belägen i låspartiets 70 centrum 79, i låshylsans 38 axiella led, ligger gaf- feln 53 inte an mot låshylsans 38 utvändiga spår 62. Urtagets 42 långsträckta parti 72 är beläget mellan låshylsans 38 splines 64 och urtagets 42 låsparti 70.The recess 42 extends in the axial extent of the locking sleeve 38. The recess 42 is provided with an elongate portion 72 with substantially parallel opposite first wall surfaces 74, which are located at a distance greater than both the diameter of the pin 40 and the clearance of the spline joint 64, 66, 68. In this way the pin 40 is avoided. in the first position lies and rubs against the first wall surfaces 74 of the recess 42. The elongate portion 72 merges into a locking portion 70, which has spaced apart opposite second wall surfaces 76, which have a radius substantially corresponding to the pin 40. radius. The second wall surfaces 76 of the locking portion 70 11 are located at a distance from each other which exceeds the diameter of the pin 40. The locking parity 70 is placed so in relation to the splines 64 of the locking sleeve 38 that when the pin 40 is located in the center 79 of the locking portion 70, in the axial joint of the locking sleeve 38, the fork 53 does not abut the outer groove 62 of the locking sleeve 38. located between the splines 64 of the locking sleeve 38 and the locking portion 70 of the recess 42.

När låshylsan 38 ska förflyttas från det första läget till det andra läget, så styrs först förbränningsmotom 4 och den elektriska maskinen 6 så att ett väsentligen momentlöst tillstånd uppkommer mellan ringhjulet 20 och planethjulhållaren 22. Därefter manöv- reras tryckluftcylindem 54 så att gaffeln 53 förskjuter låshylsan 38. Urtaget 42 forflyt- tas då från ett läge där tappen 40 är närmast låshylsans 38 splines 64 till ett läge där tappen 40 är nära låspartiets 70 centrum, i låshylsans 38 axiella led. När låshylsans 38 splines 64 kommer i ingrepp med planethjulhållarens 22 splines 68 uppstår ett moment på låshylsan 38 vilket resulterar i en kraft i dess omkretsriktning, dvs vinkelrätt mot urtagets 42 utsträckning. Låspartiets 70 andra väggytor 76 kommer då i kontakt med tappens 40 yttre perifera yta som därmed centreras i låspartiet 70. Det är alltså inte viktigt att gaffeln 53 manövrerar låshylsan 38 till exakt rätt position eftersom utform- ningen av urtagets 42 andra väggytor 76 medför att tappen 40 automatiskt intar rätt position. När tappen 40 befinner sig i centrum 79 av låspartiet 70, i låshylsans 38 axi- ella led, ligger gaffeln 53 inte an mot låshylsans 38 utvändiga spår 62 och ingen frik- tion uppstår därmed mellan dessa komponenter. I låshylsans 38 omkretsriktning behö- ver däremot inte tappen 40 vara centrerad i låspartiet 70 för att gaffeln 53 inte ska ligga an mot låshylsans 38 utvändiga spår 62.When the locking sleeve 38 is to be moved from the first position to the second position, the internal combustion engine 4 and the electric machine 6 are first controlled so that a substantially torque-free state arises between the ring gear 20 and the planet gear holder 22. Thereafter, the compressed air cylinder 54 is operated so that the fork 53 displaces the locking sleeve. The recess 42 for fl is then moved from a position where the pin 40 is closest to the splines 64 of the locking sleeve 38 to a position where the pin 40 is close to the center of the locking portion 70, in the axial joint of the locking sleeve 38. When the splines 64 of the locking sleeve 38 engage the splines 68 of the planetary gear holder 22, a moment occurs on the locking sleeve 38 which results in a force in its circumferential direction, i.e. perpendicular to the extent of the recess 42. The second wall surfaces 76 of the locking portion 70 then come into contact with the outer peripheral surface of the pin 40, which is thus centered in the locking portion 70. It is thus not important that the fork 53 maneuvers the locking sleeve 38 to exactly the right position since the design of the recess 42 second wall surfaces 76 40 automatically assumes the correct position. When the pin 40 is located in the center 79 of the locking portion 70, in the axial direction of the locking sleeve 38, the fork 53 does not abut against the outer groove 62 of the locking sleeve 38 and no friction thus arises between these components. In the circumferential direction of the locking sleeve 38, on the other hand, the pin 40 does not have to be centered in the locking portion 70 so that the fork 53 does not abut against the outer groove 62 of the locking sleeve 38.

För att kunna förskjuta låshylsan 38 axiellt från det andra till det första läget styrs för- bränningsmotorn 4 och den elektriska maskinen 6 så att ett väsentligen momentlöst tillstånd uppkommer mellan ringhjulet 20 och planethjulshållaren 22. Vid det moment- lösa tillståndet kommer låspartiet 70 i urtaget 42 att kunna lämna tappen 40, så att lås- hylsan 38 kan förskjutas axiellt med hjälp av gaffeln 53.In order to be able to displace the locking sleeve 38 axially from the second to the first position, the internal combustion engine 4 and the electric machine 6 are controlled so that a substantially torque-free state arises between the ring gear 20 and the planet gear holder 22. In the torque-free state the locking portion 70 enters the recess 42 to be able to leave the pin 40, so that the locking sleeve 38 can be displaced axially by means of the fork 53.
